About this content

This short series explains how your body gets and uses energy. You will learn about metabolism, the chemical reactions that break down food and build up your body. You will also see how ATP, the cell's energy currency, stores and releases energy. The series touches on oxidation, reduction, heat transfer, and why some reactions happen faster than others. You should have some background in basic biology and chemistry first.
